The M-100 Series Single Channel Digital Process Meter was designed for applications where the temperature, voltage or current of the sensor's output needs to be displayed. This 16-bit, 4-digit LED display is simple to program; can be calibrated to read Fahrenheit, Celsius, Engineering units, Analog Voltage, Analog Current or Resistant. Easily mounts on 1/32 DIN. The M-100 comes standard with peak-hold functions, the ability to retransmit the analog signal to a control system or data logger, plus an internal relay for alarm.

The M-100 is a miniature panel-mount digital process meter in a 1/32 DIN format, designed to display and process signals from temperature sensors, pressure transducers, and other process instruments with standard analog outputs. Its compact footprint makes it well suited for space-constrained instrument panels in aviation, motorsport, and industrial equipment.
1/32 DIN Format and Panel Integration
The 1/32 DIN standard defines a panel cutout of 24 x 48 mm, which is one-quarter the face area of a 1/8 DIN instrument. This allows multiple M-100 meters to be installed in the same panel space typically occupied by a single larger instrument.
In applications where panel space is limited, this higher density enables operators and system designers to monitor multiple process variables—such as temperature, pressure, and other critical parameters—within a compact footprint.
Input Flexibility and Configuration
The M-100 accepts a wide range of standard process inputs, including:
Thermocouple types J and K
RTD PT100
Millivolt and voltage inputs from transmitters and transducers
The input type is selectable during configuration, allowing the same M-100 unit to be used across different applications. This flexibility simplifies system design and allows a single hardware platform to support multiple measurement requirements.
